regulator: max8660 - fix a memory leak in max8660_remove()
In max8660_probe(), we allocate memory for max660. In max8660_remove(), current implementation only free rdev which is a member of struct max8660. Thus, there is a small memory leak when we unload the module. This patch fixes the memory leak by passing max660 to i2c clientdata, and properly kfree(max8660) in max8660_remove().
